This invention relates to improvements in "vehicle Wheels and particularly to adapted to embody a continuous rubber re silient member formed in one piece and placed between an inner and outer ring, one slidable over the other in such a .inanner and with such construction to sustain the weight of the vehicle and aiiord ample resilienihr and elasticity between the inner and outer ring in order to compensate for and overcome the shocks or jolts due to the u'heels riding over uneven. surfaces. The device is further designated to be securely protected from external. wear and contact thus insuring a dericcwhich'will he ot du- 'ralileconstruction and free from crystallize tion and one which will not be subject to theirarying ponditions due to expansion or contraction o u ingr to heat or cold. The device is t'urlher ada 'ited to he dis iosed hetueen the inner and outer ring; under an expansive pressure. "whereby it will sustain thh'load oi the vehicle mounted on the wheels under all normal conditions.

Al further chiect of the invention is to produce a sin'lple and iiu-ntpensi've device and vetone which will he exceedingly effective tor the purposes for which is designed. 1 These objects l' accomplish by means oi such structure and relative arrangement of the parts as Will fully appear by a perusal of the following specification and claiur.

On, the drawings similar ciilaracters of reference indicate corresponding parts in the several views.

lleiterring now more particularly to the characters of reference on the drau ings the numeral 1 designates the hub of the Vehicle thenumeralrl the spokes thereof and the numeral 3 the telly. Secured to thefeli'y 3 is a channehshapcd rim i provided sit-spaced points with depending 5. {fipaced from the rim '--l an ouler :n,l ;iliary rim 6 provided with recesses 7. i

flhe n nneral S designates a rubber member disposed in staggeredrelation and provided at each a pox with a h in ring or ferrule 9 vulranized to the rubber.

The humeral 10 designates; the side plates adapted to receive bolts ll'which project through 10 together as one member. The

side plates 10 are adapted to slide over the sides of the channelshaped riiu elto prevent trio entering into the interior equipn'lent'.

Disposed through the lower row 7' and ferrules flare screw pins 18 adapted to screw into n'o'jecting shoulders it on the-inside of the Cll2tnIl6l-SlltlPQtl rim 4-. T he member 8 at a point adjacent to each ferrule 9 is 1.)rovidcd with a square shoulder 15 adapted to fit into thcrecesses 5 and 7 in order to prevent the'memher 8 by any chance from slipping out of position and also to save Wear on the hearing points and other parts. in the other side of each ferri'lle 9 is a projectin; lnunper or shock absorber 11'; which clears the rim 3 a suiiicient distance l'r ali'ord proper rosii nu 3,

Connecting curl! of the nunipers flli to the adjacent square shoulders 15 are truss or supporting webs 17 ilorn'ied as an integral part ofthe balance oi the structure, the .;l'uuctiou of which members 1'? to prevent the *ujll'llJQI'S l5 and it from stretching out ition or wearing with. the operation of tlu device.

As can readily be seen the foregoing structure provides a rubber resilient united equipment within and encircling the wheel which bears on the inner and outer rims, such inner and outer rims carrying the re silient member in equal proportions. The enlarged shoulders the point of hearing; resting in the recesses are held in position by the said recesses and the bolts 13.

As 'will be further noted, the structure of the member 8 disposed in staggered relation tion and also to keep dust and dirt as described and extending alternately from the inner and outer rim forms a complete and continuous suspensory and resilient meznher both to maintain the Weight of the vehicle and also to permit. oi the vertical motion. of the Wheels and at the same time present a resilient and elastic support to overcome the jolts when encountering the unevenness of the ground surface. In ad dition to this the shock absorbers 16 receive any of the direct radialstra'in against the Wheel and prevent any undue amount of friction against the other parts. As before stated the members 1? keep all the. parts in fixed and true position necessary to perfect operation.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the objects of the invention as set-forth herein.

. While this specification sets forth in etail the present and preferred construction of the device, still in practice such devis tions from such detail may be resorted to' i asdo not form a departure from the spirit of the invention.

Having thus described/my invention what i I claim as new and useful and desire to secure by Letters Patent is:

A device of the character described comprising. an inner and outer rim, a continu-' Ous resilient member disposed between said rims and secured to each, each of said rims a SAMUEL JOHNSTONE:
